We are using Zimbra 8.6.0 and all clients are connecting via Webinterface.

I'v been searching the net for a suitable solution for our need, but didn't found any working options.

We are looking for a way to adapt the content of the outgoing Meeting Request mail when scheduling a meeting with external invites. We should end up with 2 kinds of Meeting Requests: one standard with the basic text (out of the box - should remain) and one adapted for specific meetings where the text should be customised to our needs.
